Re: [9fans] lp bind strangeness

Why don't you run /386/bin/ns in lp before it's many binds and before it
runs lpdspooler to see what it is that you have?

/bin/lp rebuilds its /bin from scratch at its start but uses stuff you've
bound onto to do it.

Another thing to do woule be to comment out binds in your namespace.local
till things start working again and then work backwards.

Hi,

I cannot work out what is going on.

I have been using lp to print via a remote BSD printer for months.

I have added a /lib/namespace (attached) but I cannot see how
this harms anything.

NB. my /usr/local/sys/lib/lp/spooler only contains the binaries for forsyth's
smb print client.

Now when I try to print I get:
	lpdspool: '/bin/rc' directory entry not found
On closer inspection the following code from /rc/bin/lp is being run:

if (~ $RESET '') {
	switch ($SPOOLER) {
	case -;	echo spooler does not exist for $LPDEST >[1=2]
		exit 'no spooler'
	case *;	bind -b $LPLIB/spooler /bin
		if (~ $#* 0) $SPOOLER
		if not $SPOOLER $*
	}
}

it seems that the bind is causing /386/bin/rc to disapear from /bin.

I cannot see how this can be possible. If I change the bind -b to a bind -a
then it works as expected.

It cannot be any of my mounts as lp rebuilds /bin's mounts itself
and I have nothing mounted over /386/bin or /rc/bin for that matter.

I thought I understood union directories - obviously not :-(
